PRIME MONEY MARKET
1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
Prime Money Market seeks to earn the highest level of current income
while preserving the value of your investment.
2. WHAT IS THE FUND'S INVESTMENT STRATEGY?
The fund buys high-quality, cash-equivalent securities. These securities
are short-term obligations of banks, governments and corporations that are
payable in U.S. dollars.
The weighted average maturity of the fund is expected to be 90 days or
less.
Additional information about Prime Money Market's investments is
available in its annual and semiannual reports. In these reports you will
find a discussion of the market conditions and investment strategies that
significantly affected the fund's performance during the most recent
six-month period. You may get these reports at no cost by calling us.
3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?
*An investment in the fund is not a bank deposit and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.
*Although the fund seeks to preserve the value of your investment at $1.00
per share, it is possible to lose money by investing in the fund.
*Because cash-equivalent securities are among the safest securities
available, the interest they pay is among the lowest for income-paying
securities. Accordingly, the yield on this fund will likely be lower than
funds that invest in longer-term or lower-quality securities.
